[ANN][GAP] Gapcoin - Prime Gap Search - New Math Algo - CPU / GPU - Zero Premine

[AizenSou]

Why is there only one pool to mine Gap ?

doesn't that affect the mining process or the blockchain integrity ?

nonce-pool doesn't have more than 50% nethash. Don't worry.

[bsunau7]

Anyone else been keeping an eye on testnet?

Difficulty is rising pretty fast, which means some serious mining from a very small base is happening.

Could very well be the dev working on a GPU miner.  He mentioned it a few posts up.

I see a difficulty below 17. Thats <100k pps total.

Let me show you how to optimize the miner:

My I7-4770k with 8 threads, stock-miner:
pps: 31821 / 31160  10g/h 4473 / 3429  15g/h 0 / 0

Now go on and build your own libgmp from source. When done, run the tune utility for optimum results. Copy your final libgmp.so.10 to /usr/local/lib/.

Now we're at:
pps: 34039 / 34041  10g/h 6077 / 4479  15g/h 0 / 0

Optimizing sieve size:
open src/main.cpp

line 252:
  1048576);

to
   8 * 1048576);


and line 256
  500000);

to
  15000000);

make sure to also change the shift, otherwise you wont be able to submit most blocks! You could specify it on command line, but this is safer:

line 128:
  uint16_t shift = (opts->has_shift() ?  atoi(opts->get_shift().c_str()) : 20);

change to:
  uint16_t shift = (opts->has_shift() ?  atoi(opts->get_shift().c_str()) : 23);


Now its mining at
pps: 38276 / 37068  10g/h 5156 / 5265  15g/h 0 / 0


Lets also add the tuning for Haswell AVX2:
open Makefile and set

OTFLAGS   = -march=core-avx2 -mtune=core-avx2 -O3
(if you have a haswell, of cause)

Results:
pps: 39691 / 39553  10g/h 6059 / 5635  15g/h 0 / 0

Oh yeah. 20% for free.

Thanks to riecoin my gmp is already custom compiled and tuned.  I only mentioned testnet as the diffidently was high and was increasing at a steady rate.

Interesting that you get some performance out of SIMD with the code as is.  One of the first things I did was to compile with "-ftree-vectorize -mavx2 -ftree-vectorizer-verbose=5" to see what auto-vectorising found.  It didn't find much (any?) to vectorise as most of the size of the loops aren't know at compile time (there are trick you can use however) or a non-uniform step being used.

Regards,

PS.  The fact that GCC couldn't vectorise what should be very conducive to vectorising is a good avenue to work on for speed-ups.

Its not only the vector extensions that are added, its switching between march=native to everything up to core-avx2. And O2 to O3. I dont know what exactly did the trick, has to be something thats added here.

Wouldn't be in any hurry to build it, likely might need some changes.

Note connection string should be similiar.

Hi there,

i've managed to build a experimental gpu miner.
It got me about 200,000 pps with one R9 280x without any overclocking or powertune.

Currently the miner is very experimental and needs to be tested,
therefore I published the source code on github.

The miner is a hybrid version of eXtremals fermat test and GapMiners sieve.
The sieving is calculated on the cpu and the fermat tests are running on the GPU.
Currently it is very (host) memory hungry about 1GB and you have to use one instance
per gpu device.

You can get it with:

Code:

git clone https://github.com/gapcoin/GapMiner.git -b gpu-miner
cd GapMiner
git submodule init
git submodule update

It was built against amd app sdk v2.9 but maybe works with other versions too.
You can edit the Makefile to change the sdk destination directory.

I will merge nonce-pools stratum changes, and probably fix some bugs
at the weekend, and then create some binaries within the next week.

Tell me where and gpu miner himself with the exe file?

You either:

a) wait a week
b) compile it yourself.

Code:

git clone https://github.com/gapcoin/GapMiner.git -b gpu-miner
cd GapMiner
git submodule init
git submodule update

Wow, that was QUICK! I'm pretty impressed by it!
